Tow Ready T-One Vehicle Wiring Harness by Draw-Tite, Hidden Hitch and Reese
Can be used with 5-pole, 6-pole or 7-pole adapters.
Installation: Connection point is located in the black electric junction box in the rear cargo area on the passenger side of the vehicle. A 7.5 amp fuse is included to activate the port in the electric box. The 4-pole trailer connector will be stowed in the jack storage compartment on the driver's side.
Tech Tip: It is always a good idea to apply a small amount of grease to all electrical connections to help prevent corrosion.

Today on this 2010 Honda Odyssey, we are going to install part number 118438 from Tow Ready. The first thing we need to do is get to the rear of the vehicle. We are going to open up the back hatch. And the first thing that we need to do is remove the rear threshold right here. We will start off by removing the tie-down anchor points right here. And they just unscrew. Alright, and there is a series of clips on the top right here. We will go ahead and undo those. And there are some on the backside here we can simply just pull out with our fingers. Alright, now we are going to do the same thing with this panel here, but we are not going to take it all of the way off. We are just going to loosen it up so we can get behind it. We have one more anchor point that we need to remover here too. We are going to take our lid off of our jack storage compartment and we are going to pop it loose too. And we just need to move just that little bit. That is all we need. 1:07
Alright, getting back to our passenger side of the vehicle, we will show you where the port is for you to plug in the t-one connector. Alright, we are looking at the junction box here. It is in the top right hand corner. We are looking at it, basically facing out the back of the vehicle. We will take our t-connector and we are just going to plug it right into the socket here. Find a nice place for the module. We are just probably going to stick it back here somewhere. Then we are going to take our white ground wire and we are going to attach it to this ground right here. Alright, we will go ahead and leave that alone now. We are going to run our 4-pole wire here, along the factory harness back over to the other side. We are going to slip it underneath the plastic and hide it inside the jack storage compartment. Alright, once we have that accomplished, we will go ahead and just zip-tie the wires to secure everything together. At this point, we can go ahead and start popping the interior panels back together. 2:18
With that, our install is basically complete. We will go ahead and show you how to use it now. First off, when you are not using it, this whole wire harness will stay inside the jack storage compartment. And everything will be hidden out of the way. And when you need to use it, just go ahead and pull out a little bit of the length, go ahead and set it down here. The door shield is plenty thick it will not hurt anything if you shut the door on it. Just make sure that you stay away from the latch though. OK, we shut the hatch. Now we can go ahead and just pull out what we need to reach down to our hitch. We are done with the wiring harness out back. Let us go up to the front of the vehicle where the fuse panel is. And it is going to be on the passenger side of the vehicle. You just want to go ahead and just pull out this lid. This slot right here is where our fuse will go. Alright, now that we have our fuse in the panel, let us go ahead back to the 4-pole and test to make sure everything works. 3:10
We will test our 4-pole by taking our ground clamp and connecting it to the white wire. Then we will test our running light first, that will be the brown wire. OK, then we will try our left turn which will be the yellow wire and then right turn, which will be green. And now test our brake signal, which will be the yellow and green wire. OK, with that it looks like our test works just fine. And that will finish our install for part number 118438 from Tow Ready on our 2010 Honda Odyssey.

Product received promptly at a fair price. Installed trailer wire kit in about 1 hour 15 minutes without any trouble on my 2009 Odyssey. Most of the time was reinstalling the fiberglass panels as the fasteners had stayed in the metal frame. I did view the on line installation video prior to my installing. Would recommend the kit to anyone. Sorry I didn't take any jpegs of installation.25808

I was in a hurry to get the item but did not want to pay for the overnight shipping. I contacted customer via email and asked them to get it to my house before that Friday (I ordered Sunday). The customer service rep emailed me right away thanking me for contacting them and they would process the need ASAP. The next day early in the morning I breath a sign of relief when I see my tracking number and confirmation that the product was sent! That was awesome. I got it Thurdays and it took me 10 minutes to install with easy instructions. I watched the instruction video prior to getting it and it walked me right through what was needed. I didn't need any tools and everything was in the package! The materials were top rate and it was VERY convenient not to have to splice wires and try to figure the lighting specs out. This is the second time I have ordered from etrailer.com and I would recommend anyone to them. Thanks ETRAILER for making it an easy transaction and installation. Sincerely, L. Murdock 25317

Another win for the Honda engineers. With the power distribution center in the back of the van there was no need for splicing or complicated wiring, just plug it in, route and secure the wires, install the fuse and button it all back up.25004

Outstanding. Ordered it online Wed and it came Saturday. Installation video was a great help for project. In fact the video was so good, I didn't really use the written instructions. Installation took about 1/2 hour with no problems. The video made mention of using a trim tool - I used a dandelion extractor from my gardening tools which worked fine.15792

This product was complete and trouble free. I am not an electrician, and besides changing my own oil, not much of a mechanic. However, with the videos and the detailed instructions, I was able to install this myself in about 40 minutes! I recommend you guys to everyone who I know is purchasing a hitch, etc. I can't believe anyone would pay someone else to do the installations that you outline so easily. After I installed the hitch and wiring, I put my tools away, and felt like the Master Mechanic! 13348

The wiring harness is clearly quality made, and easily installs exactly like the video shows. I like the built-in connector cover. When the harness is to be used, it is removed from the jack storage area and simply run out the back door, which is closed on the wires. I don't much like that, and would prefer some way to get the connector permanently outside the vehicle where it can be secured near the hitch, as on most vehicles, but maybe that's just not practical on the Ody.8012

Wiring Installation Excellent product and good directions from the video. I installed this on my 2005 Honda Odyssey, and no lie it took less than 15 minutes. (I watched the video 2-3 times so I had a good idea of what I was doing) No special tools needed, and I am not the most mechanically inclined. It also comes with the fuse, that goes in the front of the Honda, so that was a good bonus.3322

Solid Product at an Easy Price I must admit, I'm a weekend mechanic and was a little hesitant to dive in to this project. I've worked with plastic parts that just "snap" together/apart before. My experience has been that they are flimsy and break easily. However, the install video from eTrailer.com gave me reassurance that I just might be able to do this. I did!! It wasn't the 20 minutes that some have reported, but it wasn't over 45 minutes AND everything went back together. Hooray!! I had a little trouble with a few of the plastic snap grommets that hold the trim pieces on. Some stayed in the body mounts when the trim panels were removed. I just used some needle nose pliers and was able to pop them out and put them back in the trim before reinstalling. I'm going out on a limb and giving this product 5 stars for Reliability and Performance, even though I just installed and haven't used it yet. But there's certainly no argument that the price was great, I saved myself the cost of paying an installer, and I got to "love" my van a little more. Thanks eTrailer for the great prices and the wonderful install videos. I'll be sure to visit again when I need something on your product list.1951

Excellent Product and Video I think your videos are brilliant! (Someone deserves a raise) They really made the job of installing the wiring easy. I bought, and will soon return, a wiring harness from a national chain that did not have the T-one connector and had very vague instructions. They would have had me splicing wires…totally unnecessary when the van is pre-wired for a plug-in harness!!! Thanks to your video I did not install theirs. After trying theirs, I bought yours. It really was easy. 15-20 minutes. Also, seeing the same year and model van helped to find the hidden snaps for the interior, that saved me some time and left the van in better shape (I would have left many marks and scratches trying to get the covers off) I will recommend etrailer.com to anyone. 966

I had everything taken apart and put back in about 10 minutes. The dealership wanted $150 for this part and another $150 to install it!!! I will be back next time I have any towing needs and will highly recommend your web site. Thanks, Brian783
